Retinoic Acid and Bone Morphogenetic Protein Signaling Synergize to Efficiently Direct Epithelial Differentiation of Human Embryonic Stem Cells
25 Oct 2007
Abstract excerpt
Human embryonic stem cells (hESCs) can differentiate to various somatic lineages, including stratified squamous epithelia, although the molecular mechanisms of epithelial specification from hESCs currently remain undefined. Here, we demonstrate a novel, stage-specific effect of retinoic acid (RA) on epithelial differentiation of hESCs. RA strongly upregulated expression of keratin 18 and the transcription factor...
